A false color image of the measles virus. Arizona Department of Health This week, clinical researchers at the Mayo Clinic announced some promising early results from a clinical trial that turned a killer into a therapy: their work harnessed a modified measles virus to attack a specific type of cancer. A larger clinical trial is still ongoing, but the people running this trial decided to describe two of the patients who received the virus, one of whom ended up in remission. It's important to note that a short-term remission in one of the two patients who are described here doesn't come anywhere close to being a general cure for this type of cancer.
